KNOXVILLE, Tenn. — An out-of-work truck driver accused of opening fire at a Unitarian church, killing two people, left behind a note suggesting that he targeted the congregation out of hatred for its liberal policies, including its acceptance of gays, authorities said Monday.

A four-page letter found in Jim D. Adkisson's small SUV indicated he intentionally targeted the Tennessee Valley Unitarian Universalist Church because, the police chief said, "he hated the liberal movement" and was upset with "liberals in general as well as gays."

Adkisson, a 58-year-old truck driver on the verge of losing his food stamps, had 76 rounds with him when he entered the church and pulled a shotgun from a guitar case during a children's performance of the musical "Annie."

Adkisson's ex-wife once belonged to the church but hadn't attended in years, said Ted Jones, the congregation's president. Police investigators described Adkisson as a "stranger" to the congregation, and police spokesman Darrell DeBusk declined to comment on whether investigators think the ex-wife's link was a factor in the attack.

Adkisson remained jailed Monday on $1 million bond after being charged with one count of murder. More charges are expected. Four victims were hospitalized in critical condition.

The attack Sunday morning lasted only minutes. But the anger behind it may have been building for months, if not years.

"It appears that what brought him to this horrible event was his lack of being able to obtain a job, his frustration over that, and his stated hatred for the liberal movement," Police Chief Sterling Owen said.

Police said Jim D. Adkisson carried a 12-guage semiautomatic shotgun into the church in a guitar case.

Authorities said Adkisson's criminal record consisted of two drunken driving citations. But court records reviewed by The Associated Press show that his former wife obtained an order of protection in March 2000 while the two were still married and living in the Knoxville suburb of Powell.

The couple had been married for almost 10 years when Liza Alexander wrote in requesting the order that Adkisson threatened "to blow my brains out and then blow his own brains out." She told a judge that she was "in fear for my life and what he might do."

Calls to Alexander's home were not answered Monday, and the voice mailbox was full.

In Adkisson's letter, which police have not released, "he indicated ... that he expected to be in there (the church) shooting people until the police arrived and that he fully expected to be killed by the responding police," Owen said. "He certainly intended to take a lot of casualties."

Witnesses said the attack was cut short after some church members tackled the gunman and held him until police arrived.

The Unitarian-Universalist church advocates for women's rights and gay rights and has provided sanctuary for political refugees. It also has fed the homeless and founded a chapter of the American Civil Liberties Union, according to its Web site.

Owen said authorities believe the suspect had gone to the Unitarian church because of "some publicity in the recent past regarding its liberal stance on things."

Owen did not identify the publicity, but the Rev. Chris Buice, the church's pastor, is a frequent contributor to the Knoxville newspaper.

"In the midst of political and religious controversy, I choose to love my neighbors as myself," Buice wrote in an op-ed piece published in March. "Ultimately, I believe that tolerance, compassion and respect are the qualities we need to keep Knoxville and East Tennessee beautiful."

Confession A police affidavit used to get a search warrant for Adkisson's home said the suspect admitted to the shooting.

Adkisson "stated that he had targeted the church because of its liberal teachings and his belief that all liberals should be killed because they were ruining the country, and that he felt that the Democrats had tied his country's hands in the war on terror and they had ruined every institution in America with the aid of the major media outlets," investigator Steve Still wrote.

Adkisson told authorities he had no next of kin or family. He lived about a 20-minute drive from the Unitarian church — one of three in the Knoxville area. The church is in an established neighborhood of older, upscale homes and several other houses of worship near the University of Tennessee.

The police chief said the suspect bought the shotgun at a pawn shop about a month ago, and he wrote the letter in the last week or so. A .38-caliber handgun was found in his home.

About 200 people from throughout the community were watching 25 children performing "Annie" when the suspect entered the church, pulled out a semiautomatic shotgun and fired three fatal blasts.

Church member Barbara Kemper said the gunman shouted "hateful words" before he opened fire, but police investigators said other witnesses didn't recall him saying anything.

A burly usher, 60-year-old Greg McKendry, was hailed as a hero for shielding others from gunfire as other church members rushed to wrestle the gunman to the ground. Police arrived at 10:21 a.m., three minutes after getting the 911 call and arrested Adkisson.

No children were hurt, but eight people were shot, including the two who died — McKendry and Linda Kraeger, 61.

Gun wrestled away
When the first shot rang out at the rear of the sanctuary, many church members thought it might be part of the play or a glitch in the public address system. Some laughed before turning around to see the shooter and his first victims covered in blood.

Jamie Parkey crawled under the pews with his daughter and mother when the second and third shots were fired. He saw several men rush the suspect.

"I jumped up to join them," he told AP Television News. "When I got there, they were already wrestling with him. The gun was in the air. Somebody grabbed the gun and we just kind of dog-piled him to the floor. I knew a police suppression hold, and I sat on him until police came."

Parkey's wife, Amy Broyles, was visiting the church to see her daughter in the play. She said Adkisson "was a man who was hurt in the world and feeling that nothing was going his way," she said. "He turned the gun on people who were mostly likely to treat him lovingly and compassionately and be the ones to help someone in that situation."

Investigators were reviewing several video recordings of the performance by parents and church members. Owen said police would not release the videos or Adkisson's letter until they have been analyzed for evidence.

Adkisson, who faces his next court hearing Aug. 5, was on active duty with the Army beginning in 1974. Army records show he was a helicopter repairman, rising from a private to specialist and then returning to private before being discharged in late 1977.
